How about tripling up?

I second this.Pretty much the only way I'd trust running laser diodes would be in series (all components of a series circuit see the same current, no matter what)
But you must be sure that all the diodes are 100% electrically isolated from each other.
Boost drivers will probably not like the huge increase in forward voltage drop, but simple drivers like the LM317 can handle voltages up to 35v.
Red and IR diodes die closed, violet diodes might be 50/50... If you want to double violet diodes I suggest connecting them in series if you can.Do diodes die open most of the time or closed? I would be concerned about one diode dying and killing the other by taking on the full current.
Here is an link to a driver setup that is suposed to make doing this safer. I havn't read it yet but here you go.

Yeah... but in that schematic each LD has its own current limiting
resistor being driven by the 5 Volt fixed Voltage Regulator...

So are you saying I should just use drivers?
